(1) Any dealer, whose gross turnover of sales during a financial year exceeds twenty five thousand rupees, may, notwithstanding that he is not liable to pay tax under section 8, apply in the prescribed manner to the prescribed authority for registration under this Act.

(2) Every dealer who has been registered on application made under this Section shall, for so long as his registration remains in force, be liable to pay tax under this Act.

(3) The registration of a dealer on application made under this Section shall be in force for a period of not less than three complete years and shall remain in force thereafter unless cancelled under the provisions of this Act.

(4) Subject to the provisions of sub-Section (3), a dealer registered on application made under this Section may apply in the prescribed manner, not less than six months before the end of a year, to the authority which granted him his certificate of registration for the cancellation of such registration to take effect at the end of the year in which the application for such cancellation is made, and the said authority shall, unless the dealer is liable to pay tax under this Act cancel the registration accordingly.

When the gross turnover of sales of any dealer registered on application made under this Section has, for three successive years after the period of three years referred to in sub-Section (3), failed to exceed the taxable quantum, the prescribed authority may, after giving the dealer a reasonable opportunity of being heard, cancel registration of such dealer.
